An object reference is required for the nonstatic field, method, or property
'LevelInheritance.Person.Display()'

I am attempting to learn OOP. The book uses C++ examples. I am trying to
convert the code to C#. C# doesn't like the statement Person::Display();
in
the Student class. How do I need to modify this to work in C#? Thanks
for
your help.

using System;

namespace LevelInheritance
{
public class Person
{
protected int m_ID;
protected string m_First;
protected string m_Last;

public Person()
{

m_ID = 0;
m_First = "\0";
m_Last = "\0";
}

public virtual void Display()
{
Console.WriteLine("ID: " + m_ID +
"\rFirst: " + m_First +
"\rLast: " + m_Last);
}

public void Write(int ID, string First, string Last)
{
m_ID = ID;
m_First = First;
m_Last = Last;
}
}

class Student: Person
{
protected int m_Graduation;

public override void Display()
{
Person::Display();
Console.WriteLine("Graduation: " + m_Graduation);
}


public void Write(int ID, string First, string Last, int Graduation)
{
Write(ID, First, Last);
m_Graduation = Graduation;
}

public Student()
{
m_Graduation = 0;
}
}
